Description

Quick-freeze deep-etch image of rows of carrier vesicles lined up along the cytopharyngeal microtubular ribbons. These vesicles arise from early endosomes as clathrin coated vesicles and are about 100nm in diameter. Vesicles lose their coats before binding with the dynein motors that link them to the microtubules. They tend to lie on the anterior side of the ribbons along with the discoidal vesicles. Carrier vesicles eventually dock on acidosomes and fuse with these. Acidosomes are late endosomes. TEM taken on 5/24/88 by C. Schroeder with Zeiss 10A operating at 80kV. Neg. 12,000X. Bar = 0.5µm. This image is suitable for qualitative analysis. There is a high resolution version of this image in the library (CIL:40506) which is available for quantitative analysis.
